Our clients say:

The people here are very nice, helpful, and extremely honest. They don't try to sell you products you don't need, and they are detailed in explaining steps to take when cleaning your pool. I am always greeted by staff with a smile. My pool started off as a swamp... Its 20x40 in size; in ground. It is now almost a clear blue, all because of the helpful advice and directions from the staff. They could have easily scared me into thinking I needed their maintenance service by saying it was a task best left for professionals, but instead, listened to my needs and respected my wishes of needing to stay within my budget. I would never go anywhere else!

Kudos many times over to Underwater Pool Masters. I purchased a home in Hopkinton in 2011. UPM had performed the pool inspection that summer as part of the home purchase.
